Numeral 1 indicates the main frame of the machine which may beof any suitable construction, shown comprising horizontally disposed rails 2, provided with standards 3, 3 at opposite ends. .The frame at one Serial No. 670,284.

end is adapted to be attached to or located adjacent to frame 4 of acan seaming machine. Means are provided to feed contain.- ers, such as can bodies, A, having either one or both ends open and; disposed in a horizontal position to be fed tomeans for raising such can bodies to a vertical position with their open ends upwardly disposed, to

be pushed into the seaming means to secure the closures B thereto. In Figs. 1 toSthe body feeding means comprise an endless belt or conveyer 5 shown mounted between rollers 6, 7, 8, journaled upon the main frame. An idle pulley 9 carried upon a lever 10 pivoted at. 11 upon the mainframe, and operated by spring 12, serves to maintain desired tension inconveyor belt 5. At the sides ofbelt 5 are locatedspaced walls 2 ,supported bythe rails 2, whereby the containers or can bodies are guided- Said conveyor belt may be driven continuously in any desired way. I have shown adriving shaft 13 having gear 14 in mesh with gear 15 secured on shaft :16 journaledin suitable bearings onthe main frame, whichshaft is provided with gear17, in mesh with gear 18 on shaft 6 of roller 6, whereby the conveyor belt 5 may be driven continuously. The can bodies may be delivered to the conveyor to lie in a horizontal position thereon by any suitable means or manually. The conveyor ,is adapted to feed the can bodiesto a transferrer 19 rotatively carried by shaft 20journaled in suitable bearings onithe main frame. The 'transferrer is adapted to be rotated tosucces sively raise the can bodies delivered thereto from a horizontal to an upright position so that their open ends will be elevated into a position to receive closures or covers B to be seamed to the body. The transfer 19 may be of any desired construction and is shown comprising spaced fingers 'having curved projections 19 that are adapted to operate inspaced slots 21 in a plate 22 secured upon the main frame in substantial alignment with the upper run of conveyor 5 to receive the can bodies therefrom, (Figs. 7 and 8 The transferrer 19 is shown provided with stops 19 to obstruct the can bodies as they are advanced to the transferrer by the conveyor. In the body. receiving position the transferrer is. located as indicated in Fig. 7

with its armssubstantially within the slots 21 of plate 22, and the fingers 19 below. hen the transferrer is rotated to turn the can body to a vertical position, with its open end uppermost, the fingers 19 will obstruct the advance of can bodies by the conveyor until said fingers are again lowered, (see Fig. 7). In the example illustrated the t-ra-nsferrer 19 is rotated back and forth for the purpose of alternately receiving the can bodies and turning them upwardly. For such purpose I have shown shaft 20 provided with a gear 23 in mesh with a rack 24 that is pivotally connected at 25 with a reciprocative rod 26 that is operated by a cam 27 secured on shaft 6. By preference, rod 26 is provided with resilient means to actuate the rack 24 for which purpose I have shown said rod made in two parts, 26, 26 having relative movement, and provided with an interposed spring 28, 6), shown coiled around rod part 26 that is slidable in a bushing 29, carried by a cylinder containing said spring, the rod part 26 having a piston-like head or stop 31 between which head or stop and the bushin 29 the spring 28 is located. The rod part 26 is shown secured by a nut or head 32 to cylinder 30 (see Fig. 6). Air in cylinder 30 between heads 31 and 32 aids rod part 26 in pushing rod part 26 to actuate the rack in one direction, the spring 28 actuating the rack in the other direction. A port 30 in cylinder 30 permits flow of air into and from the cylinder. A spring 33, shown coiled around rod part 26, bears against bushing 29 and against bearing 34 for rod part 26*. The rod part 26 is shown provided with a slotted head 35 slidable on shaft 6 and provided with a projection 36 operative in the cam groove 27 of cam 27, 5). hen said cam is rotated, the rack 24 will be reciprocated to rotate transferrer 19 back and forth, the springs 28 and 33 resiliently resisting operation of the rack by cam 27, so that the transferrer will not injure the can bodies. Vhen the transferrer 19 is rotated to raise a can body to vertical position, the latter is brought to rest at its side against a wall or stop 37 (Fig. 7). Said wall or stop 37 may be adjusted with respect to the transferrer by means of slots 37 in the base of the wall and screws 38 shown passing through said slots and secured to the main frame part 3*, (Figs. 6 and 7).

When a can body is presented on end with its open end upwardly disposed it will be in position to be transferred to any suitable place, such as to seaming mechanism to se cure the closure or head 13 to the body. In the example illustrated, I have shown a turret 39 that is carried by a shaft 40 journaled in the frame 4, which turret may be rotated step-by-step by any well known mechanism utilized in can seaming machines. The turret is shown provided with spaced receivers or pockets 41, radially disposedand having their outer sides open to receive the can bodies which rest on the platform 39. I provide means to push the can bodies from the transferrer into the turret. In the eX- ample illustrated, the pusher or plunger 42 is located in register with a pocket 41 of the turret and is shown comprising a suitable head upon a reciprocative rod 43 guided by hearing 44, supported by the frame part 3 and adapted to be reciprocated to push the can bodies from the transferrer into the pockets of the turret. Any suitable means may be provided for reciprocating pusher or plunger 42. I have shown a forked arm 45 pivotally supported on shaft 46, journaled in bearings on the main frame, the forks of which arm receive lateral projections 47 extending from rod 43. The shaft 46 is shown provided with a crank arm 48 pivotally connected with a block 49 slidable on a rod 50. The rod 50 has a stop 51 against which a spring 52 bears, said spring also bearing against block 49, the latter being re tained by nut 53 on rod 50, whereby said rod may resiliently push the block 49 to operate the pusher or plunger 42. The-rod 50 is pivotally connected at 54 with a crank arm 55 shown pivotally supported at 56 on the main frame, which crank arm is shown pro vided with a projection 57 cooperative with a cam 58 on shaft 16. Cam 58 is timed to cause operation of pusher or plunger 42 through the parts 55, 50. 48, 46 and 45 so that when a can body has been presented by transferrer 19 in position in register with a receiver or pocket 41 of the turret said pusher will push the can body into said re: ceiver, and will recede from the transferrer which will operate to receive another can body and present it in register with a receiver of the turret just after the pusher has been retracted from relation to the trans-' ferrer. 7

When a can body has been pushed by pusher 42 from the transferrer into a receiver of the turret, the closure B for the open end of the can body willbe placed on said body. The closures B may be of suitable form to be seamed to the edges of the can bodies at their open ends, which closures may be retained stacked in a magazineor support 59 of any suitable or well known character, (Fig. 2), from which the closures may be fed upon the successive can bodies in the turret by hand operation, or by any suitable or well known means adapted for the purpose. hen a can bodywith its closure B laid thereon has been carried around by the turret to a suitable position, it will be brought to rest respectinr seaming devices of any suitable or well known character, not forming a part of my present invention as to structure. I have illustrated spaced seaming rolls 60 supported{overa suitable part of the turret anddrlven by mtermeshing gears 61 carried by sl1at'ts 62,

which parts may be supported and rotated in any desired manner to cause the seaming rolls to act uponthe edges of the closure and the can body to seam them togetherpasindr cated in Fig. 9. Any suitable meansmay be provided for elevating the air-bodies with their closures to'the seaming tools, such as by means of a retiprocative littercindicated at 63 adapted to beoperated bya reciprocative rod 64; to be actuated in anv'suit able way to raise and lower the canbodies when the turret comes to 1QSt,W Ifilg 2)f The seaming devices and litter 63, whichd'orm part of the seaming mechanism, will be caused to operate in relationto the step-bystep movements of the turret to cause seaming of the closure to thecan body at each stop of the turret. i 1

After the closures have beenseamed to the can bodies, the latter may be ejected from the turret by any suitable means and may be received upon a conveyor to carry them away, or may be delivered in any other suitable manner. Guards'65 are shown arranged around the turret and at the delivery point of wall 66 whiclrobstructs the can bodies, (Fig. 6). Where closures are to'be applied to both ends of the same can, they may be delivered to. aconveyor 5?, supported similarly to the conveyor 5, one roller for the conveyor 5 being indicated at'6", (Figs; 1, 6 and 7). The conveyor S inaybe operated in consonance with the conveyor 5by means of a sprocket chain 67 [operatingupona sprocket wheel 68 on-shat't of roller 6 and upon a sprocket wheel 69 on the shatt 8 of roller 8. When the can bodies or containers having the closures or heads secured at one end are delivered upon conveyor 5, they will be turned on their sides so that their then open ends extend rearwardly and will be fed by said conveyor successively to a second: transterrer associated with a second turret and seaming devices of the character herein described. which transt'errer will operate to turn such can bodies upwardly, with their open ends uppermost, and their previously closed ends downwardly disposed, in position to be pushed by a corresponding pusher 42 into the associate turret, upon which open ends of can bodies the closures or bottoms B will be placed and seamed to the -an bodies in manner before described. The arrangement described enables the continuous operation of containers or can bodies to have their closures or heads applied and steamed at opposite ends withoutany manual handling being required from the time they are first placed upon conveyor 5.

Instead of using a belt-like conveyor to feed the bodies or containers A to the transferrer, the. bodies may be fed successively in any other desired way. In Figs. 12 to 15 a reciprocat'ive bar 7t) is suitably guided alongthe rails 2and is shownprovided withspring'pressed dogs 71 pivoted on bar at 72 and controlled by springs 73, (Fig. 14). i The dogs 71 projectthrough a slot-74 longitudinally disposed in a guiding plate l 75 supported by rails-2 and on which can bodies or containers may slide; The dogs 71 s rve to puslrthe bodies to l'lill'lSfGl'lGl' 19. A "ail 7 6 supported "above. bar 70 is provided with back stops 77 pivoted to rail 76 aud depending into thepath of the bodies A to resist backward thrust "of the latter when the dogs71 slide reversely under the can bodies; Stops 78 on rails 7 6 limit upward thrust of th'eback'stops'? 7. The can: bodies or containers slide upon the plate 75 betwe'enthe'spaced walls 2 wherebythe bodies are guided to the transferrer.- :Thebar 70 may be recip'rocated in any "desired way, such as by means of link 79 pivotally connected with said bar and pivotally coiinectedwvith a rocklever 80 that is pivotally supported at 81 on bracket 82; said lever being pivotally connected to a link 83 that is pivotally connected at 84 with-a crank 85 ona shaft 86 supported by the main frame. Shaft 86 'n'iay be rotated by chain andsprocket 87, '88 or in any-other dGSlIGCl way in relation to'the i step-by-step rotation or rocking of transferrerlt). I a i In Figs. 12. 13 and 15n1odilied forms of means for reciprocatingpusher or plunger 43 are shown as follows: The rod; 50 that extends from lever 45is pivotally connected with horizontally "disposed crank arm 55 pivoted at 56 and actuated by projection 57 and cam 58011 shaft 58 to be rotatedin any suitable way.

In accordance with my invention, the can bodies or containers, having one or both ends open, may be delivered in any suitable way to the conveyor to lie thereon in a horizontal position with the open ends that are to be provided with closures extending rearwardly respecting the transterrer. An advantage isthat the can bodies may be fed directly from a can body forming machine they are produced, without requiring intermediate handling. The conveyor will feed the can bodies to the transferrer either successively and continuously bymeans of the conveyor belt 5, or successively and step-bystep by the reciprocative bar70. In either case, when the transferrer is in body receiv ing positionthe pusher or plunger 42 will be at one side thereof and the transterrer will be operated to raisethe can body thereon trom a horizontal position to an upward position in front ot the pusher, with an open end of the can uppermost; in register with the turret. \Vhen the transferrer comes to rest with a can body in the last named position, the pusher will operate to push the can body into a receiver of the turret and the pusher will retreat so that another can body may be placed by the conveyor upon the t-ranst'errer. In the example illustrated, the transt'errer will be located in. a position to receive another can body or container, to be turned to an upright position, and so on for each body or.container to be provided with a closure. \Vhen a can body or container has been placed in a receiver or pocket-of the turret. a closure B will be placed on the open end of the can body and the turret will rotate a step for each can body. After the can bodies or containers with closures thereon are carried around by the turretto the seamin mechanism the can bodies will be presented in position to have their closures seamed to the bodies by theseaming mechanism, after which the headed can bodies will be discharged from the turret successively to any desired receiver, as upon the conveyor 5. Heretot'ore, so far as I am aware, can bodies have been fed to seaming mechanism either manually or by chutes for standing the can bodies on end upon a conveyor that would teed such bodies to the seaming mechanism. Vhere small can bodies, and those having irregular shapes, such oblong in Cross section, are placed upon a conveyor they are liable to be tilted out or position .with the result that they are not always t'ed properly to the seaming mechanism or the turret thereof, necessitating manual attention to the feeding of the bodies to the seaming mechanism. By means of my invention the objection to icedmg can bodies or containers to a conveyor standing .on end \vlth their open ends extending upwardly is overcome, since the can bodies may lie on their sides until they are turned on end in position conveniently to be pushed to the seaming mechanism or the turret thereof, thereby overcoming danger that the can bodies will be inaccurately or irregularly fed to the seaming mechanism, whereby the operations are expedited and loss of can bodies or containersby improper feeding is minimized.

While I have illustrated a transt'errcr for the can bodies that is adapted to be rotated or rocked backand forth to receive the can bodies and turn them onend in position to be )USllCCl to the seaming mechanism, it is to be understood that my invention is not limited to the particular construction for back and forth operation of the transferrer, since the same could rotate continuously in one direction,and that changes may be made in the details of construction set forth, within the scope vot' the appended claim, without depart ing from the spirit of my invention.

Having now described my invention, what I claim is: y l

The combination of means to feed containers successively, a transferrer having means to receive said containers, a shaft car-. ryingsaid transferrer, a gear upon the shaft, a rack to operate the gear, a reciprocative rod to operate the rack, said rod having a plurality of members and interposed resilient means to cushion the thrusts of the rod, means to reciprocatethe rod, means to push containers from the transferrer, and seaming mechanism comprising a turret provided with receivers for the containers.
